Abstract
A microfluidic delivery device is provided. The microfluidic delivery device includes a housing electrically connectable with a power source. A cartridge is releasably connectable with the housing. The cartridge has a reservoir for containing a fluid composition and microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in an upward direction relative to horizontal. The microfluidic delivery device also includes a fan that is connected with the housing. The fan is configured to generate air flow that converges with and redirects the fluid composition dispensed from the microfluidic die in a first direction to a second direction that is different from the first direction.
